Message at 6K rpms. If you look at the any dynos you well see the drop. It is caused by harmonics and is very notice able on upgraded cams without the upgraded springs. It is even more enhanced with upgraded turbos. I would suggest that you make sure your mechanic has upgraded springs to match the JWT cams or it will hurt performance. Worst yet is that you would have to open her up again to install the right springs and that will cost you time and money.

Even a stock dyno will show the dip that I'm referring to.

**Dynoed at 371.2 rwhp. and 362.3 rwtrq. @ .9 bar on pumped 91 gas no time tweaking 3/11/31/03**
**Dynoed at 411 rwhp. and 452 rwtq. @1.15 kg. on race gas 104 no time tweaking 3/28/03 **All numbers are SAE corrected**
